ABSTRACT
Graphology is the study and analysis of handwriting especially in relation to
human psychology. Many neurological disorders like apraxia and chorea can
affect handwriting. Many psychiatric disorders like Depression, Obsessive
Compulsive Disorder, schizophrenia are also linked with handwriting change.
A unique presentation of major depressive disorder manifesting as chief
complain of handwriting change was observed in a girl who had nice
handwriting before depression. In spite of constant efforts she was not able to
revert back to her original handwriting. Her new handwritings were different
from old one in form of width and height of letters, organization and overall
presentation. She was prescribed antidepressants. Depressive symptoms were
relieved and her handwriting started gradually improving considerably
though previous level had not been achieved.
Analysis of handwriting as a tool to understand the emotional state
of person can be implicated during psychiatric assessment. The written off
science of graphology needs to be made specific and sensitive so that it could
provide more accurate results. Further research in this area is warranted.

Introduction
Since long, handwriting has been used to
identify personalities and emotional states
(Graphology) in people. [1] In the act of writing,
we make many spontaneous movements. These
movements are recorded on paper and reflect
our ever-changing emotions. This recorded
movement - handwriting - is like an open
window through which we can observe the
whole vista of a personality. Handwriting like
speech is directly connected with our thought
process. It is also particularly responsive to
emotions such as sadness or enthusiasm.
During the process of writing, we transfer our
feelings onto paper and the words that we have
shaped reflect these emotions. In fact,
handwriting is so amazingly sensitive that it can
be something of an emotional barometer.
Excitement, fear, anxiety, irritability or anger
can be seen quite clearly. [2,5] That is why an
understanding of handwriting can be so
valuable; for example if you write while you are
feeling nervous, feeling of anxiety will show up
as an almost imperceptible trembling in the
strokes of certain letters. It may not be
immediately visible at a quick glance (although
sometimes it is) but it will in all likelihood show
up under a microscope. This is because your
handwriting is the written externalization of the
vibrant activity going on inside you. It is a type
of mental photograph of your inner processes
where small quick movements reflect the inner
vibration of activity within and round smooth
movements show your feeling of relaxation and
calm. [3] This is but one aspect; there is so much
to handwriting analysis.
Graphology is the study and analysis of
handwriting especially in relation to human
psychology. In the medical field, it can be used
to refer to the study of handwriting as an aid in
diagnosis and tracking of diseases of the brain
and nervous system.[1] Every literate human has

his or her own manner of writing. There are
many peculiarities in a handwritten text’s
specific shape of letters, e.g. their roundness or
sharpness; regular or irregular spacing between
letters; the slope of the letters; the rhythmic
repetition of the elements or arrhythmia; the
pressure to the paper; the average size of
letters etc. [3] there is a long list of neurological
disorders that affect handwriting, some of
them are Congenital apraxia, Strephosymbolia,
Cerebral hemorrhage/ trauma, Encephalitis,
Paralysis agitans, Toxemia/ alcohol,
Huntington's chorea and many more. [7.8.9,10] In
various studies many psychiatric disorders are
also linked with handwriting change like
Depression, Obsessive Compulsive Disorder,
schizophrenia and other types of psychosis.

Case Report
Patient Miss N, a third year MBBS student
presented to psychiatry department with
complains of change in her handwriting since 1
year and in spite of constant efforts she was not
able to revert back to her original handwriting,
the change in handwriting took place in a
period of 2 months gradually. Patient became
increasingly worried as her grades began to fall
due to poor handwriting. Patient consulted 2
different neuro physicians without any
improvement; underwent MRI spinal cord and
MRI brain (including functional MRI), muscle
charting & nerve conduction study of right
hand (suspected as thoracic outlet syndrome
and as a diagnostic scan) which were normal.
Patient’s new handwriting (Fig.3) differed from
old (Fig.1) in following ways:
85% increase in width of letters
10% increase in height of letters
Baseline not followed as before, words
were frequently above and below the
baseline
Previously used to write 5 to 6 words in a
line but now writes only 3 – 4 words in a
line
Decreased consistency, irregular slanting,
decreased organization, decreased
connectivity of letters in words with
increased angulations.
Fluency, speed and pressure on paper were
more or less same.
On detailed interview patient revealed
that since 1 year she had conflict in form of
breaking up 5 years old love relationship with
her boyfriend mutually as he belonged to other
religion and they were afraid that their families
would not approve of their marriage. Since
then patient had complains of:
decreased participation in previously
pleasurable activities like participating in
extracurricular activities, travelling and
reading
persistent sadness of mood
disturbed sleep and appetite
preoccupation with thoughts regarding the
event
crying spells
mild anxiety off and on
For further exploration of effect of stressor on
handwriting patient was made to write on
paper while imagining on different situations;
and her handwriting evaluated and results were
interesting. On writing a letter to her boyfriend
to whom she was intensely emotionally
attached the new handwriting (Fig.2)
characteristics became much more prominent
like: (as compared to original handwriting
(Fig.1)
A 150% increase in width of letters
15% increase in height
Increased deviance from baseline
Only 2-3 words in a line
Decreased connectedness of words
Markedly decreased organization and
consistency
On writing a letter to her brother to
whom she was moderately emotionally
attached the handwriting change became less
prominent as was in case of letter to boyfriend
but on artificially creating a mental situation in
which patient continued her letter imagining
that she was telling her brother that she had
married against their parent’s will the

disturbance in handwriting again became
prominent.
On writing a letter to her teacher to
whom she had no emotional attachment the
newly acquired handwriting (Fig. 2) did not
show any further change. Premorbid
personality analysis of patient revealed that she
was introvert in nature, never used to express
anger on others even in extreme conditions,
was particularly good in studies, quoted
frequently as an ideal example in her family and
her cherished childhood memories were
focused mainly on academic achievements.
There was no history of psychiatric illness in her
or in family.
Patient was prescribed antidepressant
for her depressed mood. In the course of
events after starting antidepressant patient
again reconciled with her boyfriend and couple
became committed again. Depressive
symptoms were relieved following 1 month of
antidepressant treatment. At one month follow
up patient’s handwriting had gradually
improved (Fig. 4) but still did not attain
previous level though there were no further
episodes of worsening of handwriting. Mental
status examination was not significant for any
psychopathology. Patient took antidepressants
for 6 months and did not show any further
signs of depression. At six month follow up
handwritings were considerably improved
though still previous level had not been
achieved.

Discussion
Above patient’s condition can be discussed
under following aspects: A unique presentation
of major depressive disorder manifesting as a
primary complain of handwriting change. In
general due to lack of awareness regarding
depressive episode, attribution of it to
environmental stressors and masking of
symptoms due to good social support patient
may present with such complains. Also
prominent studies in past as well as present
times have documented handwriting change in
patient’s of depressive illnesses [4,13,14] linking it
to basal ganglia dysfunction and or and/or
deficient activity of the sensory motor cortex
and the supplementary motor area. [13]
Stressor/conflict in psyche manifesting
itself as neurological sign in form of
handwriting change warranting diagnosis of
conversion disorder which is supported by the
fact that changes become more prominent as
the stressor is aggravated. In educated people
(specially with medical background)
presentation of conversion symptoms is less
likely to be possession episodes, episodes of
unexplainable unconsciousness or
breathlessness etc, their inner conflict can seek
attention by means of such symptom as
handwriting change.

Analysis of handwriting as a tool to
understand the emotional state of person can
be implicated during psychiatric assessment.
The written off science of graphology needs to
be understood better and made more specific
and sensitive so that it could provide more
accurate results. Further research in this area is
warranted.

This review paper highlights the hidden violent and aggressive behavior in serial killers by analyzing its handwriting features. Identification of violent behavior in handwriting is very important as it has close relation with personality disorder or psychopathy and its associated crimes that can be overcome in future. Graphology is a scientific method to identify an individual’s personality, temperament, professional and intellectual behavior, social and inner capacities by evaluating and understanding patterns revealed in handwriting. Handwriting analysis describes a psycho-social-behavior like that of psychologist who emphasis on biological and psychic components interactions revealed in one’s handwriting e.g. serial killers. Graphology experts approach advanced technology and research studies to facilitate the process of handwritten images of general public data and observe the signs of violence in their graphical handwritten features. It can be used as coherent and resourceful profiling instrument to enrich the information and to assist the forensic psychologists, psychiatrists and investigators in their investigation.

Handwriting, like all other behavior, is regulated by the brain. This is typically an unconscious mechanism that is closely related to brain impulses. Any mental disorder can impair the forearm’s kinetic motions, as can be seen in the subject’s handwriting. It’s crucial to focus on how a subject write rather than what a subject write if you want to understand health and mental issues. The aim of this analysis study is to learn about the changes that occur in an individual’s handwriting characteristics during psychological problems, or when the subject is in a troubled state of mind. Calligraphy The study and analysis of handwriting, especially in relation to human psychology, is known as graphology. It has been discovered that features related to motion, time, and pressure are very useful and could be used to diagnose health and mental disorders using a manual or digital handwriting analysis approach.
... It is used as a tool by forensic graphologists to study criminal personality and can assist in criminal investigation [14]. Research by [15] from psychopath paper] shows that people having psychopathic personality disorder have dysfunctional amygdale and it is reflected in their handwriting [16]. Some researches [65] did crime analysis using Apriori Algorithm. ...

The handwriting of a human being carries the richest information which helps gain insights into one’s physical, emotional, and mental state. Graphology helps in interpreting a person’s characteristics by analyzing their handwriting. It is the investigation of a sensible state of mind at the time of writing. This gives an insight into the morality, enthusiasm, and hidden talent of the writer. The state of the cerebrum is reflected in handwriting as the signals move from the cerebrum to the fingers. This has been studied for almost 400 years. Graphology has wide applications in the fields of medicine, education, criminology, etc. Integrative graphology primarily focuses on different strokes of the written word and the relation to an individual’s personality. Holistic graphology considers the form, use of space, and movement during writing. Features of handwriting such as concavity of letters, margin, spacing, pen pressure, baseline, size of letters, loops of alphabets are considered for the above-mentioned applications. These factors lead to the analysis and study of cases based on criminology and depression which focuses on examining the handwriting of the individual and keep a track of their behavior.KeywordsGraphologyHandwriting analysisCharacteristic traitsPersonalityImage processingFeature extractionClassificationsMachine learning

In recent years, personality has been considered as a valuable personal factor being applied to many fields. Although lately some studies have endeavored to implicitly obtain user’s personality from her/his handwriting, they failed to achieve satisfactory prediction performance. Most of the related methods focus on constructing handwriting features, while the handwriting change information is ignored. In fact, user’s handwriting change could reflect her/his physical and mental state more finely, which is helpful for recognizing the user’s personality. Furthermore, the related studies may not fully use Chinese character features to analyze the change of Chinese handwriting. In this paper, we propose an effective Chinese Handwriting Change based Personality Prediction (CHCPP) model to identify users’ personalities. To be specific, we construct the handwritten character sequence based on the writing order. We then extract the Chinese character features and the visual signals of each handwritten character in the sequence to analyze the handwriting change. Meanwhile, we also construct the statistical Chinese character features based on the whole handwritten character set to assist in modeling the change of Chinese handwriting. Lastly, we utilize the handwriting change information and the statistical Chinese character features to acquire the prediction results. The experimental results show that our CHCPP model outperforms the related methods on a real-world dataset.KeywordsPersonality predictionHandwriting changeChinese character featureDeep learning

Few shot models have started to gain a lot of popularity in the past few years. This is mostly because these models grant the ability to structure the representation space (classes) using a very less amount of examples for each class. Such models are usually trained on a wide range of different classes and their examples, which allows them to form and learn a decision-based metric in the process. Non-Latin languages, especially languages such as Urdu, have a bi-linear direction of writing and are context-sensitive in nature, and are hard to recognize. Also, unlike traditional English, there is a very small amount of clean, collated, and usable data that is available for the Urdu language. In this paper, we explore a prototypical network for k-shot classification on handwritten Urdu characters. The prototypical network learns the Euclidean embeddings of the provided images and uses clusters to classify newer examples. Our improved method is able to outperform other methods of few-shot learning and is able to accurately classify both Urdu characters as well as numerals using a minimal number of examples. After comprehensive qualitative and quantitative evaluation and comparison of our proposed approach with other methods to classify handwritten text in few-shot settings, we found out that our proposed approach was typically able to beat other methods by a margin of 1% – 2% while relying on a small training set.

Every literate human have their own distinctive handwriting characteristics that is of course embedded. Handwriting is that the photograph of the inner conflicts going on. It might be used as a projective test to review part that the person resist or generally is unaware of to share. This study makes an attempt by finding out that whether or not is it attainable to spot the criminal behaviour by a person' handwriting, as a result of delinquent behaviors are extremely current among kids and adolescents yet as adults. once these behaviors reach clinical significance they place a high burden on the individual, his or her immediate encompassing and society in general, higher insight into the correlates of delinquent behavior is required so as to develop adequate bar and intervention methods matched to a private's personal risk to have interaction in antisocial behavior and skill associated risk factors. During this study 25 handwriting samples (22 males and three females) of individuals with high antisocial behaviour were analysed and compared with those of people with low antisocial behaviour and the study concludes that from a graphologist's purpose of view, the writing of an individual with high antisocial behaviour will typically be delineate as that like a brick in the wall, rather trite, with a very little rhythm, inflexibility, dull and plentiful in abnormalities.

Rigorous documentation and inspection methods are used by financial institutions to manage the risk due to information asymmetry and moral hazard. Nevertheless, the intent of the borrower of funds is not obvious. The unique nature of handwriting can to an extent be a reflection of intent. Besides the financial services sector has a highly competitive market structure. Selling of financial products is a challenge; quickly understanding financial preferences through handwriting can be used to apply concentrated efforts on ‘likely’ customers. Handwriting analysis when facilitated through machine learning methods can have wider application to address the challenges of the financial sector. The present study adopts an experimental approach to apply machine learning techniques to handwriting analysis. Identified handwriting correlates helped to map the individual into corresponding personality type. Risk preferences are mapped to the Big Five Personality Traits (Andreas Oehler, 2017). Thus the paper detailed the evaluation of handwriting features for one of the Big Five Personality Traits viz. Extraversion. The results yielded 7 such handwriting features which were evaluated with machine learning techniques on 112 samples collected through personally administered questionnaire. Extraversion is associated with perceived financial behavior as ‘risk seeker’. We found that individuals who scored high on extraversion had no risk no reward philosophy, were likely to over spend and were inclined to invest in risky financial products like mutual funds.

Expert readers exhibit a remarkable ability to recognize handwriting, in spite of enormous variability in character shape-a competence whose cerebral underpinnings are unknown. Subliminal priming, combined with neuroimaging, can reveal which brain areas automatically compute an invariant representation of visual stimuli. Here, we used behavioral and fMRI priming to study the areas involved in invariant handwritten word recognition. Compared to printed words, easily readable handwritten words caused additional activity in ventral occipitotemporal cortex, particularly in the right hemisphere, while difficult handwriting also mobilized an attentional parietofrontal network. Remarkably, however, subliminal repetition effects were observed across printed and handwritten styles, whether easy or difficult to read, both behaviorally and in the activation of the left visual word form area (VWFA). These results indicate that the left inferotemporal VWFA possesses an unsuspected degree of fast and automatic visual invariance for handwritten words, although surprisingly this invariance can be reflected both as repetition suppression and as repetition enhancement.

Basal ganglia dysfunction is supposed to play a part in the pathophysiology of obsessive-compulsive disorder (OCD). A new computer aided technique for the analysis of hand movements, allowing the detection of subtle motor performance abnormalities, was applied in this study of patients with OCD and healthy controls. Using a digitising graphic tablet, hand motor performance was studied in 22 unmedicated patients with OCD and compared with 22 healthy controls. All subjects drew superimposed concentric circles with both the right and the left hand, in addition to writing a given sentence, their personal signature, and letter sequences in four different sizes. Kinematic parameters were calculated to quantify hand motion. Patients with OCD had significant impairments of handwriting performance, reflected by lower peak velocity (sentence t=3.6; p=0.001; signature t=2.8; p=0.01) and micrographia (sentence t=3.4; p=0.002; signature t=2.5; p=0.02), compared with controls and shortened acceleration phases per stroke (sentence t=2.4; p=0.02; signature t=4.1; p=0.000). By contrast, in repetitive drawing, patients with OCD had higher peak velocity than healthy controls (group x task interaction p<0.01). There were no significant differences in left and right hand performance between groups. Patients with early versus late age of onset differed in handwriting parameters, such as handwriting consistency. Greater severity of obsessions and compulsions correlated with increasingly poor handwriting performance in patients with OCD. A subtle motor dysfunction in OCD can be detected with a digitising tablet. The findings show handwriting impairments in patients with OCD, in line with the assumption that basal ganglia dysfunction is part of OCD pathophysiology. Repetitive motor pattern performance was not impaired, but rather tended to be even better in patients with OCD than in controls. The findings also support the concept that patients with OCD with early versus late age of onset differ in pathophysiological mechanisms and basal ganglia dysfunction.

To evaluate the ability of two graphologists and two practising internists not trained in graphology to differentiate letters written by subjects who have attempted to commit suicide by self-poisoning and healthy volunteers, we performed a maximal blind controlled study vs. healthy volunteers. Forty fully recovered patients who had attempted to commit suicide and 40 healthy volunteers wrote and signed a short letter or story not related to the parasuicide or their mental health status. The evaluators classified the 80 letters as 'suicide' or 'no suicide' in an intention-to-treat analysis. Letters expressing sadness were subsequently excluded for a per-protocol analysis. Correct diagnosis of suicide and of healthy controls was made in, respectively, 32 of 40 and 33 of 40 letters by the graphologists and in 27 of 40 and 34 of 40 letters by the internists. After the exclusion of 12 letters expressing sadness, the sensitivity, specificity, positive predictive value and negative predictive value were, respectively, 73, 88, 81 and 82% for the graphologists and 53, 89, 80 and 71% for the internists. Both classified the letters with significantly more effectiveness than chance (p < 0.001) with no statistically significant difference between the two groups of evaluators. We concluded that graphological analysis is able to differentiate letters written by patients who attempt suicide from those written by healthy controls. This technique shows an acceptable degree of accuracy and could therefore become an additional discharge or decision-making tool in Psychiatry or Internal Medicine.

Despite evidence of cognitive impairment and difficulties in performing daily activities among elderly people with major depression, studies implementing objective performance-based evaluation of functional deficits in this patient population are scarce. With the aid of a computerized device we examined functional handwriting performance among elderly patients with mild Major Depressive Disorder (MDD) in comparison with controls. Participants were 20 elderly participants with mild MDD and 20 matched controls. Both groups performed four functional writing tasks with a computerized system. Kinematic measures were: in-air time per stroke (temporal), stroke width (spatial), pressure applied (pressure). A MANOVA yielded statistically significant between-groups differences for the four writing tasks across the temporal, spatial and pressure measures. A univariate ANOVA revealed that the significance was due to differences between mild MDD and controls on the pressure measure in all four tasks. Moderately significant correlations were found in all tasks between in-air time and pressure while writing and the GDS score, and between the in-air time of three tasks (except writing one's name) and the Mini-Mental State Examination (MMSE) score. Handwriting pressure, and temporal and spatial measures of the task of writing one's name allowed us to classify 84.2% of the participants correctly. Computerized evaluation of handwriting, a daily task, was found to be sensitive to altered performance among participants with mild MDD, and was correlated with cognitive impairment and depression status. The theoretical importance and practical implications of handwriting process measures are discussed.

Wills signed by elderly people are often contested on the grounds the the signature is different from their earlier specimen signatures. Neurological disease, which can affect handwriting, is very common and progressive amongst elderly people. Handwriting change due to old age and neurological disease is poorly understood. To better understand this subject, we carried out a large methodical study based on almost 200 handwriting specimens of Parkinson patients and age-matched controls. Interestingly, our findings indicate that some of the handwriting changes which occur in these populations tend to resemble forgery indicia although upon close inspection they are distinguishable from them. Thus, document examiners are urged to exercise caution in assessing purported forgeries on wills and other documents signed of written during older age or a writer suffering from neurological disease.

In the last decade, major changes in our understanding of basal ganglia functions have occurred. Traditionally the basal ganglia were considered to be involved only in the modulation of movement. Recent research has suggested that the basal ganglia also take part in complex fronto-subcortical networks that have an important role in cognition reward, and mood regulation. The authors review recent findings that implicate basal ganglia abnormalities in the pathophysiology of mood disorders and discuss their potential implications for future developments in the pharmacotherapy of depressive disorder.

Document examiners are often faced with difficulties in evaluating handwriting by persons under the influence of alcohol. Although numerous articles are available on the subject of alcohol influence on handwriting quality, most of them were based on empirical data such as “few” or “increased”, without any statistical evaluation. The aim of this research is to determine whether previous observations on reported effects of alcohol on handwriting are valid and to establish the predictability of observing specific effects. A total of 73 participants, who completed all steps of the experiment, were surveyed. Handwriting samples were taken before and after the consumption of alcohol. The test form, including criteria of prior studies used by document examiners, was evaluated with the help of a Olympus X-Tr stereo microscope, direct and oblique angle lighting and a video spectral comparator (VSC 2000). Measurements were done by means of digital caliper, statistics using repeated measures ANOVA, Pearson correlation, Pearson Chi square test, McNemar test and Wilcoxon signed rank test.
